Huang Jing is rich in medicinal value of plants, but Huang Jing harvest usually 3 ~ 4 a, 4 a invested 165,000 yuan · hm-2, with an average annual funding volume. However, with the development of modern agriculture, it was found that after the interplanting of bamboo rafts, Huang Jing not only improved the land utilization rate, but also played a short-term growth and reduced the pressure on the investment of Linxia Huangjing. The large amount of retained slag after bamboo picking is a good organic fertilizer. It can be artificially applied to the planting of huangjing, improving the soil structure and water and fertilizer conditions of the Castanea henryi forest, accelerating the circulation rate of resources, and promoting Huangjing and Castanea henryi. Growth. Through the study on the difference of yield, basic labor and labor intensity of different planting methods of P. chinensis under the Chinese chestnut forest, the experiment was conducted to select the planting method of the bamboo stalks suitable for actual production, which was actively promoted in Zhejiang Province. One acre of mountain 10,000 yuan" provides technical reference for the economic business model under the forest. 2015-2016, the central science and technology project of two kinds of forest bacteria combined cycle business model in Zhejiang Province was implemented in Qingyuan County. The project creatively combines the compound management mode of Castanea henryi-Donghuajing, Castanea henryi-R. The compound management mode of the forest-drug-bacteria of "the upper layer of chestnut + the lower layer of multi-flowered yellow essence and the thorny bamboo raft" has been formed, and good results have been achieved. 1 Materials and methods 1.1 Overview of the test site The test site is located at the Huangjing Base of the Leopard Forest, Qingyuan County, Yuyuan County, Qingyuan County, Qingyuan County, Zhejiang Province. The geographical coordinates are 118°59′10.9′′ E, 27°35′48.2′′ N, altitude. 409 m, horizontal ladder width 2 to 4 m. Red loam, subtropical climate, the average temperature of 17.6 deg.] C, the hottest months (July) the average temperature of 26.9 deg.] C, the coldest month (January) average temperature of 7 ℃, the average annual rainfall 1 746.9 mm, average relative humidity 77% The annual average frost-free period is 255 days. The forest is divided into pure forest of Castanea henryi. It is a fine family of oil scorpion, Astragalus membranaceus, and Wushou Changmang. It has a forest age of 14 a and is in a prolific period. The current diameter of the chestnut is 15.6±3.4 cm, the tree height is 6.2±1.4 m, and the average plant spacing is 4.8. m × 5.1 m, the average crown diameter 6.3 m × 6.5 m, canopy density of 0.7 to 0.8. Polygonatum is planted in November 2013, the breeding method using the tubers, spacing of 20 cm × 40 cm; planting furrow laid perpendicular to the horizontal ladder tape, after planting Qimian width 1 ~ 1.2 m, high stretch 25 ~ 30 cm, the operation groove width 30 to 40 cm. 1.2 Test materials The bamboo cultivating materials are bamboo chips which have been fermented for 40 days and have a water content of 53% to 56%. The bamboo chips are scraps of bamboo chips and bamboo powder of local bamboo processing enterprises; Gutian, Fujian, the size of the strain is 14 cm × 27 cm. 1.3 Test design and method Selecting the site conditions, slope direction, slope position and other basic cone-shaped chestnut forest under the Huangjing planting area, respectively, the overlapping species, side species, groove species (full groove species, semi-groove species) treatment, each treatment area > 2 m2, The amount of feed is 37.5 kg·m-2, and the strain is 2 packs·m-2. The planting methods for each treatment are as follows: The method of superposition: planting bamboo rafts on the surface of the yellow essence. The bamboo stalk cultivation material was planted on the surface of the planting of the yellow sorghum, and the feeding range was 20 m2 along the edge of the raking surface. Side method: planting bamboo rafts on the side of the plant. The width of the paving is 1/2 of the operating groove width to the outer edge of the kneading surface, and the length is 20 cm of the long ends of the plant. Full groove type: that is, planting yellow essence on the operation ditch perpendicular to the horizontal ladder. The length of the paving is 20 cm at each end of the planting of the yellow cultivar, and the width of the paving is the width of the operating ditch. Semi-groove type: the length of the bamboo raft is 1/2 of the operation ditch, and the paving width is the width of the operation ditch. The method of measuring the basic labor process of the bamboo planting method per unit area: the planting area of ​​each planting method is >5 m2; the workers participating in the survey are the same person, and the planting methods are basically rested for 30 minutes at the time of the measurement, and then the next planting method is carried out. Basic labor measurement time. According to the different working conditions, each planting method is divided into 6 processes, such as clearing the litter on the horizontal ladder and collecting the chestnuts in the paving area, laying materials, monoliths, sowing, covering soil and laying straw. Each process is connected in a sequential construction method. Each step was measured with a stopwatch and recorded. Dictyophora cultivation and management: each process decking after inoculation casing 6 ~ 8 cm. At temperatures below 18 ℃, plastic film covering spawn; rhizomorph mycelium into excavated, to the cover film, covered with straw or chestnut leaves; egg appeared to increase after a large number of bacteria fill water, sooner or later spray once; a tidal Dictyophora After the harvest is over, stop the water for 5 to 7 days, then pour a heavy water on the surface. Data collection: The bamboo rafts were harvested during the harvest period of the bamboo rafts, and the fresh weight was measured and recorded. Data Processing and Analysis: Data processing and analysis of variance were performed using Excel 2007 and SPSS 19.0. 2 Results and analysis 2.1 Differences in yield of bamboo rafts under different planting methods of undergrowth The yield of bamboo stalks from different planting methods was ranked from high to low: semi-groove > full stalk > side species > superimposed (Table 1). Among them, the yield of the semi-groove species and the gully species, the lateral species and the stacked bamboo rafts differed only by 39.1 g·m-2 and 40.8 g·m-2, and the difference was not obvious; the gully species (including the gully species, the semi-groove species, the same The yield is 233.7 g·m-2 and 274.5 g·m-2 higher than that of the side species and the top seed, and the difference is obvious. The results of variance analysis showed that there was no significant difference in the yield of bamboo shoots between different planting methods (F=1.419, P=0.307>0.05). Table 1 Differences in yield of bamboo rafts between different planting methods of bamboo stalk and huangjing / g·m-2 2.2 understory bamboo sun Huang Jing interplanted with different planting patterns foundation Difference between working time and labor intensity The basic labor time per unit area of ​​the planting method was the largest, the side was the second, and the groove was the smallest (Table 2). Among them, the groove type saves 137 s·m-2 than the overlap type, and saves 78 s·m-2 compared with the side species. There is a significant difference in the working intensity of each planting method. The working intensity is generally the largest, the side is the second, and the smallest is the smallest. Taking the large-scale paving and covering process as an example, the working intensity of the stacked materials due to the restriction of the paving working surface and the short-distance vertical transportation to the working surface of the cultivation material and the covering soil is obviously greater than that of the intercropping and the side species, and the labor intensity is increased. It will inevitably lead to the extension of the necessary rest time, so that the working time per unit planting area will increase and the work efficiency will decrease. Table 2 Differences in basic labor time of different planting methods of undergrowth and bamboo stalks/s·m-2 3 Conclusions and discussion 1) There is no significant difference in the yield of bamboo stalks under different planting methods. However, the overall yield of bamboo rafts was higher than that of the side species and the topping planting methods, which increased by 12.4% and 14.9%, respectively, compared with the side seed and the stacked bamboo stalks, and the planting area of ​​bamboo rafts was 3 000 m2·hm-2. According to the calculation (the same below), the fresh yield of the cultivar bamboo cultivar increased by 701.1kg·hm-2 and 823.5 kg·hm-2 compared with the side species and the superimposed species; the drying rate of fresh bamboo stalks was 10%, and the sales price of dried bamboo stalks was 200. membered meter · kg-1, were increased by 14,022 membered · hm-2,16 470 yuan · hm-2. The use of furrows to increase the yield of bamboo stalks is obvious, and it has certain positive significance in production. 2) Different planting methods of the bamboo cultivar under the forest, the planting amount of the gully species is the least, the labor intensity is the lightest, the side species is the second, and the topping is the largest. Species than the species groove side, stacked species artificial inputs decreased 114.2h · hm-2,65 h · hm-2; effective working time 8 h / person · d, labor wages 150 yuan / person meter · d, the groove Compared with the superimposed and side species, the labor cost is 2 141 yuan·hm-2 and 1 219 yuan·hm-2. The combination of labor input and labor intensity is more effective in saving labor costs. 3) test by way of different planting bamboo fungus production henryi forest intercropping Huang Jing bamboo fungus, artificial differences in volume and intensity showed that the ditch kinds of bamboo fungus cultivation methods the highest yield, lowest labor costs, significant economic benefits. Under the forest, the yellow fine interplanting bamboo carp should choose the way of gully. The difference in the promotion of different cultivation methods to the growth of Polygonatum needs further study.
